Control using INC (Incremental data method)

(1)Circular interpolation from the current stop address through the specified auxiliary point address to the end point address is executed.

(2)The center of the arc is the point of intersection of the perpendicular bisectors of the start point address (current stop address) to the auxiliary point address, and the auxiliary point address to the end point address.
